The product corresponds very well to what I expected. But the service is the Amazon, to put the enclosure I have cut a little plastic enclosure, and after installation I've realized that the speaker was not working properly. I called their customer service department stating that the vessel had been cut, they told me that it was not serious and that he replaced the product anyway, and sent me two new speakers even before I sent the others. For now it is the most efficient service that I know. Congratulations.
